The scrubber is providedwith openings through which fluid is applied to the users head. A supplycabinet automatically supplies water and hair treating fluid to thehelmet. Separate solenoid actuated valves control the flow of water andhair treating fluid from the supply cabinet to the helmet. A hydrauliccylinder and piston in the cabinet is used to move a rod having meansfor successively engaging the solenoid control switches as the pistonmoves lengthwise of the cylinder.

This invention relates to an improved automatic shampooing apparatus andhas for one of its principal objects the provision of a novel mechanicalunit designed and constructed for the purpose of cleaning, massaging andadding cream or oil to the human head :and hair.

One of the important objects of this invention is the provision of adevice of the class described which will automatically wet, soap, rub,rinse, soap, cream or oil and then finally rinse to complete a cyclewhich will result in a satisfactory operation far superior andnecessitating less time than previously done manually.

Another important object of the invention is to provide in an automaticshampooing and hair cleaning apparatus, a mixture control valve whichwill automatically provide the proper temperature of wash waterregardless of line pressure drops in either cold or hot water inlets.

Another object resides in a device incorporated into the apparatus whichwill control the speed of the operative cycles at the option of theuser.

A further object is the provision of soap, cream and oil containerswhich automatically control the output of ingredients therefrom to apredetermined amount during the cycle of operation.

A still further important object of the invention is to providesolenoids or similar valves which automatically control the passage ofthe various fluids in proper cycles.

Yet another object is the provision of a plurality of signal lightswhich indicate the working condition of the apparatus at all times.

Other and further important objects of the invention will be apparentfrom the disclosures in the accompanying drawings and followingspecifications.

The invention, in a preferred form, is illustrated in the drawings andhereinafter more fully described.

FIGURE 13 shows the control means of FIGURES 10 and 11 in a differentphase of operation and in a different position.

FIGURE 14 is a section on the line 1414 of FIG- URE 10 lookingrearwardly.

The reference numeral 15 indicates generally the control combination ofthe improved automatic shampoo apparatus of this invention, this beingconnected to a head piece or helmet 16 adapted to be fitted onto theusers head, as best shown in FIGURE 1. This head piece is mounted on anarm 17 secured to a post or support 18, having ball joint or similarconnections and also an adjustment for height whereby the same can bereadily fitted onto the head of the user for comfortable and convenientoperation.

The head piece or helmet 16 can be composed of any suitable material andhas within its frame hydraulic cylinders 19, having plungers 20connected by ball and socket joints to scrubber elements 21 (FIGURES 2and 4).

The cylinders 19 are connected by links 22 to the shaft of a variablespeed motor 23, (FIGURE 2) whereby the scrubber units will move back andforth while being operated by an eccentric 24 on the motor shaft (FIGURE5).

A wire 25 connects the motor to the control cabinet 15 and the speed ofthe motor is in turn controlled by the user from a rheostat or similarswitch in a housing 26 connected by a wire 27 to the cabinet 15. Thecontrol 26 is at all times in the hands of the user, thereby giving theuser complete control of this phase of the operation and insuring safetyand relaxation. In this manner the scrubbers 21 which are composed ofeither rubber or plastic or combinations thereof and which are sodesigned as to conform to minimum, maximum and average contours of humanheads will operate in accordance with the users wishes.

As best shown in FIGURE 4, each scrubber comprises three sectionshingedly connected at 28 with the center plate secured to the pistonshaft by means of a swivel connection. The end plates are spring loadedas at 29 in order to maintain pressure against the users head in adirection conforming to the center line of the support axis. In thismanner, practically any head contour can be readily accommodated.

Water for rinsing and soaping is supplied to the helmet from a line orconduit 30 and jets 31 placed in strategic positions within the headpiece apply water as desired.

From an inspection of FIGURE 3, it will be noted that the scrubbers 21have openings 21a therein for the purpose of allowing a desired andnecessary quantity of water, soap, cream or the like to reach the scalp.

Soap is supplied by a pipe or conduit 32 and jets 33 and oil or creamthrough a conduit 34 and jets 35. Hydraulic fluid lines 36 and 37 areconnected to the cylinders 19 for desired scrubber pressure andretracting operation respectively. These lines are also controlled bythe user. A drain pipe 38 leads from the helmet 16.

An inflatable tube 39 is attached to the head piece in such a manner asto conform to the human head above the eyes, behind the ears andcontinues on around the bottom of the neck near the shoulders, beingreinforced by a cushion 40 and adapted to be inflated by means of a handpump 41 convenient to the patron, all as best shown in FIGURES 1 and 2.This tube 39 will prevent water, soapsuds, oils or the like fromescaping from the helmet or head piece end and running down the face orshoulders. A release button 42 is provided on the pump 41 to allowdeflation of the tube after completion of the cycle and obviously thepressure in the tube can be maintained by the user to insurenon-leakage, while at the same time providing a comfortable fit.

The jets for water can be of any desired number, usually six; and thecream and soap jets are approximately the same number and spaced instrategic positions. The liquid in the cylinders 19 is controlled byfour-way solenoid valves operated by position buttons on the controlunit 26 in the hands of the user. This remote control switch allows theperson using the apparatus to increase or decrease the pressure of thescrubbers on the head or scalp, thereby resulting in a massage which canbe gentle or firm as desired.

Sterilization of the head piece can be accomplished by the use of anozone generator, whereby ozone or oxygen is introduced into the helmetin any convenient or suitable manner, or sterilization can beaccomplished by any available means.

The connections for supplying soap, water, oil etc., to

the helmet are preferably of clear plastic tubing, but obviously othermaterials may be employed.

As best shown in FIGURE 7, the cabinet 15 is connected to inlet pipesand 51 for hot and cold water respectively, and inlet pipe 52 for ozoneor other sterilizing medium, a drain pipe 53 and as best shown in FIGURE8, a power input line 54.

The cabinet 15 is provided with a cover 55 (FIGURE 7) which has a valvecontrolled by a handle 56 for an initial regulation and mixing of thehot and cold water supply; and pressure and temperature gauges 57 and 58are associated with this control valve. The hot and cold water supply isadditionally controlled by a valve 59 which controls the drain pipe fromthe head piece.

A cylindrical container 60 is provided for soap and a similar container61 is provided for cream or oil, both being in liquid form; and each ofthese cylinders has an operating piston 72 therein and solenoid operatedvalves 80 and 63 respectively in its exit line to control the quantityof soap, cream or oil sent to the helmet or head piece by the connectinglines 32 and 34 respectively.

The panel 55 is alsoprovided with a master switch 64 for current controland an associated signal light 65.

When the light 66 is operated by the switch 67, such action establishesa soap pumping operation. The twoway switch 69 in circuit with thelights 66a and 68 will establish either a soap or oil pumping operationfor a second choice through switch 100. It will be noted that the soapswitch 67 remains closed throughout the operating cycle.

Openings 70 are in the panel providing ready access to the covers of thesoap and cream containing cylinders, one of which is shown in moredetail in FIGURE 9. The switches are for the purpose of retracting thepistons in the respective containers for purposes of refilling sameafter the pistons have moved to an uppermost position in the supplyingoperation.

Referring now to FIGURE 9, it will be noted that the cylinder 60 has aremovable cap 71 for refilling purposes and a piston 72 which movesupwardly to expel soap as required. This piston is moved upwardly bywater pressure in a line 73 controlled by a solenoid operated valve 74(FIGURE 7). A rod 75 connects the piston 72 to another piston 76 in asmaller cylinder 77 fixed beneath the main cylinder 60, and anotherhydraulic line 78 allows water to enter the cylinder 77 for depressingboth pistons when the cylinder 60 is to be refilled. The line 78 iscontrolled by a solenoid operated valve 79.

When the piston 72 reaches the uppermost limit of its travel, itcontacts a position pin 45 in the cylinder cover and this in turnoperates a micro-switch 46 which in addition to operating the signallamp to indicate that a new supply of soap is necessary, also initiatesthe operation of the valve 79 through its solenoid allowing hydraulicpressure to depress the piston 76 in the cylinder 77, thereby makingroom for a new supply of soap in the cylinder 60. The cover 71 can thenbe removed and replenishment accomplished. When this is done the valve80 (FIGURE 7) is automatically operated by its solenoid assuring animmediate supply of soap to the head piece. Auxiliary hand controlvalves 81 are also provided for emergencies.

The sequence of operations is automatically accomplished by the actionof a piston 82 in a control cylinder 83 (FIGURES 7 and 10 to 12inclusive). The piston is moved to the right, as shown in these figuresby hydraulic pressure from a line 84, having a pressure regulator 85 anda pressure control valve 86 therein. When the operation is started thefour-way solenoid operated valve 87 is opened, allowing cold water fromthe main line 51 to flow through the pipe 84 to the cylinder 83, and atthe same time allowing any undesired liquid in the cylinder 83 to escapethrough the line 88 and valve 87 to drain 53. The movement of the piston82 is quite slow, as this movement controls the entire operation ofwetting, soaping, washing, rinsing, oiling or creaming and finalrinslng.

A block 89 is on the end of the rod of the piston 82, and this supportsa bracket 90 and a switch operating cam 91. The bracket 90 is fixed onthe block 89 and carries a spring pressed terminal 92 which makescontact with a pre-set switch 93 fixed on the cylinder 83 and carryingcorresponding current connections as indicated in FIG- URE 8.

The switch operating cam 91 is pivoted on the block 89 at 94 and ismaintained in position to successively operate a series of switches by aspring 95.

These switches are identified by the reference numerals 96, 97, 98, 99,and 101 (FIGURE 7).

Referring now to FIGURE 8, it will be noted that as the cam 91 movesoutwardly by the action of the piston 82 in the cylinder 83, it firstcloses the switch 96 which through its solenoid operated valve 102initiates a flow of water through the line 30, this water having beenpreviously mixed to a desired temperature by passage through the controlvalve 56a.

The switches can be spaced apart so that any desired time interval canbe predetermined, but as the block 89 progresses it will necessarilyclose the switch 97 which opens the valve 80 allowing soap to flow tothe helmet through the line 32- The flow of soap is controlled bypressure in the line 73 leading to the container 60, and through thesolenoid operated valve 74.

In the meantime the scrubbers 21 are being operated and controlled bythe user as heretofore described.

The switch 98 is for the purpose of allowing some sterilizing mediumsuch as ozone or the like to enter the helmet, and this is an optionalconstruction. Obviously, a medium other than ozone can be employed suchas any one of the various new chemical products now on the market.

Further movement of the block 89 closes the switch 99 which allows waterof the proper temperature to flow to the helmet for rinsing purposes,and this rinse water will be drained off at 38.

Next an application of cream or oil is accomplished by the closing ofthe switch 100, this opening the valve 104 and allowing the ceram or oilto pass through the tube or pipe 34 to the helmet in a predeterminedtimed amount. Finally, the switch 101 is closed which again suppliesrinse water through the solenoid operated valve 102.

The cam 91 has a roller 105 thereon which as the piston continuestowards the end of its travel will ride up on a cam plate 106 moving thecam 91 into aposition to open the switch 101, the others having beenaccordingly opened by spring action after the passage of the camthereover.

The bracket 90 has simultaneously with the previously describedoperations moved along with the block 89; and its inner extension willthen close the switch 93, the two switches 107 and 108 (FIGURE 8) havingbeen closed at the start of the operation. These switches control signallights 65, 66 and '68, indicating that the soap and oil supplies areadequate and that the desired operation is progressing satisfactorily.

The pin 45 (FIGURE 9') which is actuated when the iston 72 reaches itsupper most limit, will, when closing the switch 46, operate either oneof two signal lights 109 and 110 which indicates to the operator thatthe supply of either oil or soap respectively is exhausted. Thecontainers for soap and oil can then be readily refilled manually by apreliminary operation of the valve 79 which forces the piston down byhydraulic pressure from the water system. The switch 125 operates thevalve 79. It will be noted that water pressure through the valves 74 and104 operates the pistons 72 in soap and oil discharging movements in thecylinders 60 and 61.

The closing of the main switch 64 will, not in itself, provide an actualoperation which must be actually instigated by push button 111 in thecontrol panel. The light 65 is associated with this push button and theswitch 64 to indicate actual operation. The two-way switch 67 controlsrespectively the soap and oil supply and pilot lights 66a and 68 areprovided adjacent the switches.

The switches 107 and 108 are for the purpose of holding the circuit inoperation so long as the switch 93 remains in on position.

A visual gauge 130 which provides a water operation and temperature testpreliminary to initiation of theshampooing action is provided for thecomfort and safety of the user; and after the operator determined thatconditions are correct, this can be manually shut 01f.

A reversing switch 131 is provided for the valve 59 operating throughthe solenoid 132, and this acts in cooperation with the block 91, pin140 and stop 141. The cycle adjustment can be made slow or fast, asdesired, by means of this construction.

It will be seen that herein is provided an automatic new and usefulmechanical unit which will clean, massage, rinse and add cream or oil tothe human head and hair in a completely efficient and entirelysatisfactory manner and with a high degree of safety dependentpractically entirely upon the wishes of the user. In the event offailure of any portion of the apparatus, the operation is immediatelyeither automatically or manually discontinued, whereby even theslightest degree of possible damage is prevented.

The automatic timing hydraulically powered and the bleeding device toassure the necessary supply of soap, cream or oil after refilling, alsocomprises an important and essential feature.

No water can reach the helmet without being previously automaticallybrought to the desired temperature and the gauges, besides being at alltimes visible, are automatically controlled to insure proper pressure ofwater inside the helmet.

The water, soap, oil, etcetera, are supplied preferably to the headpiece by means of plastic, flexible pipes, but other connections may beemployed.

I am aware that many changes may be made and numerous details ofconstruction varied throughout a Wide range without departing from theprinciples of this invention, and I, therefore, do not propose limitingthe patent granted hereon otherwise than as necessitated by the priorart.
